Technical Field

The invention relates to the technical field of medical instruments, in particular to a surgical operation laser conveying system cutter head.

Background

Lasers have gained considerable attention in the field of surgery because of their very good cutting power, good coagulation and little thermal damage. The high-energy pulse laser generated by the laser is transmitted out through the optical fiber, the optical fiber enters the human body through the endoscope, the energy of the laser is transmitted into the part needing laser treatment, and effective and safe treatment is carried out on a patient by utilizing the characteristics of high energy, collimation, short action time, small heat affected area and the like of the laser. The interaction of laser light on biological tissue is the physical basis of medical applications, and the thermal effect of laser light is one of the most widely used and earliest recognized effects of laser tissue in medicine.

When a laser is used for a surgical operation, the cutting effect of the laser is greatly influenced by the blade.

Disclosure of Invention

To solve the above technical problems, the present invention provides a surgical laser delivery system cutter head to facilitate the creation and cauterization of an incision.

In order to achieve the purpose, the invention provides the following scheme:

the invention provides a surgical laser delivery system cutter head which comprises a blade and a joint, wherein the blade is arranged at one end of the joint, a through channel is arranged in the joint, and an optical fiber extends into the through channel from the other end of the joint to be in contact with the blade.

Optionally, the blade is in a right trapezoid shape, a first connecting portion is arranged on one side of a right-angle edge of the blade, one side of the oblique edge is close to the direction of the central line of the blade to form an edge portion, one side of the longer bottom edge is a plane, and one side of the longer bottom edge is converged with the edge portion to form a tool nose.

Optionally, a second connecting portion is disposed on one side of the joint close to the blade, and the first connecting portion is connected with the second connecting portion to detachably fix the blade to the joint.

Optionally, the first connecting portion is a block-shaped body protruding outward, and a first fixing hole is formed in a side surface of the block-shaped body.

Optionally, the second connecting portion is an inwardly recessed cavity, the shape of the cavity matches with the shape of the block-shaped body, a second fixing hole is formed in the cavity, the position of the second fixing hole matches with the position of the first fixing hole, and the blade is fixed to the joint by arranging a pin or a screw in the first fixing hole and the second fixing hole.

Optionally, the through channel is a step-shaped through hole, and the diameter of one side of the step-shaped through hole close to the blade is smaller.

Optionally, the larger diameter part of the stepped through hole is connected with the smaller diameter part through a tapered surface.

Optionally, adhesive is disposed between the larger diameter portion of the stepped through hole and the optical fiber.

Optionally, the adhesive is silica gel.

Optionally, the blade is made of a gemstone.

Compared with the prior art, the invention has the following technical effects:

the main structure of the surgical laser delivery system cutter head comprises a blade and a joint, wherein the blade is arranged at one end of the joint, a through channel is arranged in the joint, and an optical fiber extends into the through channel from the other end of the joint to be in contact with the blade. The blade has a cutting edge and a tip, thereby concentrating the ability of the laser to facilitate the creation and cauterization of the incision.
